Abstract. Chloropelix canariensis Lindberg, 1936, Paradorydium desertorum Linnavuori, 1964, and P. spatulatum (Naudé, 1926) are recorded from the United Arab Emirates for the first time. These species were collected from Poaceae and Compositae in northeastern part of the country. Paradorydium deserto- rum is also recorded for the first time from Israel, and P. spatulatum, from Morocco. Two new synonyms are established: Bumizana deccani Viraktamath et Viraktamath, 1989, syn. nov. = P. spatulatum; Chloro- pelix indica Viraktamath et Viraktamath, 1989, syn. nov. = Ch. canariensis. Резюме. Chloropelix canariensis Lindberg, 1936, Paradorydium desertorum Linnavuori, 1964 и P. spa­ tulatum (Naudé, 1926) впервые указаны из Объединенных Арабских Эмиратов. Эти виды собра- ны со злаков (Poaceae) и сложноцветных (Compositae) на северо-востоке страны. Paradorydium desertorum также впервые указан из Израиля, а P. spatulatum – из Марокко. Установлены два но- вых синонима: Bumizana deccani Viraktamath et Viraktamath, 1989, syn. nov. = P. spatulatum; Chlo­ ropelix indica Viraktamath et Viraktamath, 1989, syn. nov. = Ch. canariensis.

Based on available evidence, I propose to treat these two names as synonyms and extend the distribution of Ch. canariensis all the way to the Indian subcon- tinent. Pennisetum setaceum (Forssk.) Chiov. and Cenchrus ciliaris L. (=P. cenchroides Rich.) (Po- aceae) were recorded as host plants of Ch. ca- nariensis by D’Urso et al. (2019) and Lindberg (1954). Viraktamath and Viraktamath (1989) recorded Ch. indica associated with Crotalaria burhia Buh.-Ham. (Fabaceae).
